Today, many organizations acquire and implement enterprise resource planning (ERP) solutions to improve their operations performance and create value. However, they fail to achieve these objectives due to a lack of knowledge and a better estimating of all the costs related to an ERP system project. The purchasing costs of ERP systems are the most visible expense for many organizations that have adopted ERP systems, but the entire ERP lifecycle phase of implementation contains many hidden costs. As a result, institutions have long struggled with information system implementation cost overruns. This document presents the research on the various costs associated with the different stages of the life cycle of the REP project according to the literature on ERP lifecycle costs.

Speech recognition is one of the most important research fields nowadays because of its necessity in our daily lives and to raise the fields of security to the highest level, It{\^a}{\texteuro}{\texttrademark}s a task of speech processing, and our main scope in this paper is on speaker verification, which is to identify persons from their voices where the process depends on digitizing the sound waves into a form that allows the system to deal with it. The verification process is based on the characteristics of the speaker{\textquoteright}s voice (voice biometrics) and sends it to a further process to extract the features of that voice using the feature extraction method and using AI techniques to perform the task of identification. MFCC is used for the task of features extraction and obtains the spectrogram of a given voice signal where it represents a bank of information about the voice and sends it to the CNN model for further processing for training the model on that signal to verify if the voice belongs to a user in the system or it{\^a}{\texteuro}{\texttrademark}s a new enrollment.

\ Assessment, diagnosis, and cognitive stimulation of patients with different stages of cognitive impairment, including mild cognitive impairment (MCI) and Alzheimer{\^a}{\texteuro}{\texttrademark}s disease, has become a growing area of research. Recently, there has been an increase in interest in applying serious games for older people with neurodegenerative diseases. The present systematic review aims to investigate and classify serious games for detecting cognitive impairment in the elderly. In this review, searches focused on studies conducted between 2014 and 2021, of which twenty-four studies met the inclusion criteria. In this regard, we identified a few categories for the collective classification of serious games. We chose taxonomy of five classes to classify serious games dedicated to cognitive training and diagnosis among seniors: cognitive skills, objectives, game elements, motivation, and validation. We conclude that gamified techniques prove to be a valuable complement to traditional treatments because of the increased patient engagement.

\ This study examines information organization activities in the knowledge management environment. The investigation commences with the long-drawn debate on the concept of Knowledge Management and the literature that has hitherto reviewed it. Furthermore, the study delves into how conventional bibliographic information retrieval techniques and expert search systems have heretofore been applied in the organization and retrieval of digital resources and if they can be employed in the Knowledge management setting. It is contended that though the procedures, tools, and techniques are effectual and productive, they cannot be utilized in a knowledge intensive environment. Accordingly, the study puts forth a generic knowledge management framework that can be applied in a knowledge management setting. In addition, it proposes novel research gaps in the context of information organization.

Historical newspapers are a source of research for the human and social sciences. However, these image collections are difficult to read by machine due to the low quality of the print, the lack of standardization of the pages in addition to the low quality photograph of some files. This paper presents the processing model of a topic navigation system in historical newspaper page images. The general procedure consists of four modules which are: segmentation of text sub-images and text extraction, preprocessing and representation, induced topic extraction and representation, and document viewing and retrieval interface. The algorithmic and technological approaches of each module are described and the initial test results about a collection covering a range of 28 years are presented.

The Semantic Distributional Model is based on the frequency of contexts of use of language terms in large open corpus such as the web, to establish similarity or the relationship between words. These relationships or similarities can be used to add terms when expanding queries. The idea explored in this paper is that, for queries in closed collections of text documents, a posterior filter based on the restricted vocabulary of the collection can improve the effectiveness of automatic query expansion. This idea is developed and evaluated in publicly available benchmarks presenting promising results.

Today, enterprises use a variety of applications to manage day-by-day business activities using a large centralized database. Since a huge amount of data stored in this centralized database produced by the daily use of several systems, it is important to integrate decision-making tools to analyse and interpret these business data. For this purpose, Data Mining is a powerful technology that promote information and knowledge extraction from large databases. In this paper, we present an agent-based approach for extracting business association rules from centralized database systems. This approach combine paradigm of multi-agent system and the association rules as a data mining technique to build anefficient model. It is relying on the intelligent partitioning of data to make the execution of business association rules in a parallel and distributed way from a large centralized database. To validate our approach, we applied it during the realization of a real case study on ERP database at the National company of Well Services (ENSP)using JADE platform with machine learning WEKA toolbox for association rules mining. The developed system has been compared with the classic association rules algorithms and has proved it is more efficient and more scalable. The main objective of our work is to improve and accelerate the process of extracting association rules by business through centralized database systems. As a result, the decision process of these systems becomes more improved.

\ Facing an unprecedented explosion and growth of Information and Communication Technology (ICT) signal the overwhelming dependency on the digital library (DL). Over the years, libraries spent a great amount of investment to subscribe to various digital resources such as online databases, electronic journals, electronic books and other digital resources. However, previous studies reported that the use of DL is underutilized; hence undermining its original purposes and making it harder for the libraries to justify their investment on DL resources. It is reported that users prefer to use free online resources compared to the DL resources. The lack of DL usage is credited to the lack of DL engagement and the impact of contextual factors leading to DL engagement. Yet, not much is known about the contributing factors of DL engagement as well as its impacts. Therefore, the purpose of this paper is twofold: (1) to introduce the concept of Digital Library Engagement, and (2) to discuss at the conceptual level on the determinants and impacts of digital library engagement and development of a conceptual framework. In order to develop the conceptual framework, the study adopted a systematic literature review approach of over 100 papers. Grounded in previous literature on DL, the contributions of this paper are as follows: first, the paper provides insight on the new concept of digital library engagement; second, the paper proposes\

\ Cloud computing is the latest technology in both hardware and software. The cloud computing architecture offers a number of services including the SAAS, PAAS and IAAS. When customers specify their technical and economic needs, cloud computing helps them satisfy their request at the lowest possible cost and the best quality of resources. This paper presents a new approach for resource allocation (RA) in cloud computing. Its architecture is based on multi-agent system (MAS) and distributed constraint satisfaction problems (DCSP) where variables and constraints are distributed among multiple agents. In MAS, each agent makes his choice via a distributed negotiation to satisfy the global objective which is looking for the best solution to the users{\textquoteright} needs. The present work highlights a new approach that is based on hybridizing (DCSP) and (MAS). This decentralized approach is designed to solve a number of problems such as resource allocation and planning cloud-computing systems.

\ Latent Dirichlet Allocation (LDA) is the technique most commonly used in topic modeling methods, but it requires the number of topics generated by LDA to be specified for topic recognition modeling. Except the main iterative methods based on perplexity and nonparametric methods, recent research has no simple way to select the optimal number of topics in the model. Aiming at appropriately determining the number of topics and then optimizing the LDA topic model, this paper proposes a non-iterative method for automatically determining the number of topics. The clustering method is based on fast seeking and locating density peaks. This method transforms the traditional topic cluster number selection problem into clustering problem and thus can be used to optimize the topic recognition model for news texts. It does not need iterative optimization and can simplify model development. This method uses Word2Vec for word embedding on corpus text to explore the superior performance of word-related relationships and to express the implicit semantic relationship between topic corpora. Then, using a clustering algorithm that quickly searches for and finds the cluster peaks; the word vectors after word embedding are clustered to obtain the number of word vector clusters after word embedding. The number of clusters is used as the number of topics in the text. Finally, the experimental results show that the proposed method enjoys better precision and F1 value than the perplexitybased method, and is suitable for the identification of the number of topics in corpora in different sizes. This method can effectively find the appropriate number of topics from the news text dataset and improve the accuracy of the LDA theme model.

The Vehicle ad hoc Networks (VANET) are attracting more and more manufacturers and researchers{\textquoteright} attention. Many challenges must be addressed before VANETs can be successfully deployed. The most challenging issue in VANETs is designing of routing mechanisms and efficient medium access control protocols so that safety related and other application messages can be timely and reliably disseminated through VANETs. The aim of VANET routing protocols is establishing of an efficient route between network nodes that should adapt to the rapid changes in the network topology. However, routing protocols in VANET is a challenging issue, mainly due to the rapidly changing topology of vehicles and frequent fragmentation in the network. In this work, we review the most frequent routing protocols for VANETs and then we provide a taxonomy of these protocols based on the used relay selection technique. We compare and discuss these routing protocols according to different criteria. Moreover, we discuss several issues and prerequisite that should be considered when designing VANETs routing. Finally, we highlight the most important aspects and future directions that could be explored in the design of a new Geocast routing solution for vehicular routing algorithms as a contribution for further work.

This paper describes an approach that exploits links in XML retrieval. The proposed approach consists of reranking the set of documents returned for a given query by considering three sources of evidence namely, the relevance scores w.r.t query of a document neighbours, the text of the anchor links, and the document title tag. Our approach is evaluated on INEX 2006 collection. The results showed significant improvements of the retrieval performances.

\ Nowadays, Big Data has reached every area of our lives because it covers many tasks in different operation. This new technique forces the cloud computing to use it as a layer, for this reason cloud technology embraces it as Big Data as a service (BDAAS). After solving the problem of storing huge volumes of information circulating on the Internet, remains to us how we can protect and ensure that this information are stored\  without loss or distortion. The aim of this paper is to study the problem of safety in BDAAS, inparticularly we will cover the problem of Intrusion detection system (IDS). In order to solve the problems tackled in this paper, we have proposed a Self-Learning Autonomous Intrusion Detection system (SLA-IDS) which is based on the architecture ofautonomic system to detect the anomaly data. In this approach, to add the autonomy aspect to the proposed system we have used mobile and situated agents. The implementation of this model has been provided to evaluate our system. The obtained findings show the effectiveness of our proposed model. We validate our proposition using Hadoop as Big Data Platform and CloudSim, machine learning Weka with java to create Model of detection.

Methods: In this article, an enhanced BM25 mathematical approach is proposed to retrieve the most query relevant literature from clustered Biomedical literature bank with query expansion from MeSH. The clustered biomedical topics are analyzed with different pre-processing methods and term-weighting functions and found the best values for the tuning parameters K1, b, K3 and the right combination of pre-processing and term weighting functions for improving the query performance in terms of Average Precision, Mean Average Precision and R-precision. Novelty/Improvements: In this approach, the existing best match retrieval technique is normalized with the calibrate constants K1 = 1.3, b = 0.75, K3 = 1.2 and the significant terms are identified with comparison of MeSH for query expansion. The retrieval performance is improved in terms of Mean Average Precision and R-precision

In the present computer world Wireless Sensor Networks are playing a major role in sensing environment, health care and embedded systems category. In WSNs sensors are the nodes which are deployed randomly and in a wide spread manner. Data can be transmitted to the controller by the sensors at periodic intervals. As the network is dynamic the number and behavior of nodes vary randomly and identifies the nodes which are active are selected and the nodes which are idle are neglected. In WSN, the topology of the network is dynamic, it is necessary to identify the neighbors in the proximity and coordinate data acquisition at the controller. In any network reliability is an important issue which deals with stability under mobility, low delay, more life time, optimal route and other optimizations.

However, the shortest routes do not always provide the best performance, especially when there are congested nodes along these routes. In this paper, we propose an on demand delay based quality of service routing protocol (AODV-D) to ensure that delay does not exceed a maximum value. First in this paper, we compare the performance of two prominent on demand routing protocols AODV and DSR in stressful situation. As the performance of AODV has been found better in our simulation than DSR, we decided to modify AODV routing protocol to provide quality-ofservice. This protocol takes into consideration MAC layer channel contention information and number of packets in the interface queue in addition to minimum hops. The protocol is implemented and simulated using GlomoSim simulator.

Indeed, the discussion process plays an important social task in collaborative learning practices.

Considering these benefits, current educational organizations incorporate on-line discussions into web-based courses as part of the very rationale of their pedagogical models. However, in-class collaborative assignments are usually greatly participated and contributed, which makes the monitoring and assessment tasks by tutors and moderators time-consuming, tedious and error-prone. Specially hard if not impossible by human tutors is to manually deal with the sequences of hundreds of contributions making up the discussion threads and the relations between these contributions. Consequently, tutoring tasks during on-line discussions usually restrict to offer evaluation results of the contributing effort and quality after the collaborative learning activity takes place and thus neglect the essential issue of constantly considering the process of knowledge building while it is still being performed.

The complex data relation of the distributed data systems is reduced based on graph theory. The complexity of distribution is decreased significantly. In the multitree model, each user has a maximum access range corresponding to its multitree. It is integrated naturally with security.

Indeed, the discussion process plays an important social task in collaborative learning practices. Participants can discuss about the activity being performed, collaborate with each other through the exchange of ideas that may arise, propose new resolution mechanisms, justify and refine their own contributions, and as a result, acquire new knowledge. Considering these benefits, current educational organizations incorporate on-line discussions into web-based courses as part of the very rationale of their pedagogical models. However, in-class collaborative assignments are usually greatly participated and contributed, which makes the monitoring and assessment tasks by tutors and moderators time-consuming, tedious and error-prone. Specially hard if not impossible by human tutors is to manually deal with the sequences of hundreds of contributions making up the discussion threads and the relations between these contributions. Consequently, tutoring tasks during on-line discussions usually restrict to offer evaluation results of the contributing effort and quality after the collaborative learning activity takes place and thus neglect the essential issue of constantly considering the process of knowledge building while it is still being performed.

Such sensor-rich environments should be able to offer distributed and dynamic access to resources according to context information, such as user{\textquoteright}s location and time. In this scenario, the access control decisions should be based also on context information. However, as context information represents real-world situations, it is associated with certain quality indicators, such as up-to-dateness and precision, which can directly affect the access control decisions. Furthermore, enforcing user{\textquoteright}s privacy policies on context information can decrease the quality of context (QoC) information used for making access control decisions. Quality of context has in fact a strong impact on the suitable behavior of contextbased access control models.

We introduce and study a novel Kendall-tau rank aggregator and a simple aggregator called PrOpt, which we compare to some other well known rank aggregation algorithms such as average, median, CombMNZ and Markov chain aggregators. Our results show that the relative performance of aggregators varies considerably depending on how the input rankers relate to the ground truth.}, keywords = {Kendall-tau rank aggregator, Rank aggregation algorithms, Rank aggregators}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-70350655572\&partnerID=40\&md5=9105bd74059b6e4c04845776bb7c00d9}, author = {Adali, S. and Hill, B. and Magdon-Ismail, M.} } @article {76, title = {Multimedia knowledge representation for automatic annotation of broadcast TV archives}, journal = {Journal of Digital Information Management}, volume = {5}, year = {2007}, note = {Cited By (since 1996):1Export Date: 10 July 2014}, month = {2007}, pages = {67 - 74}, abstract = {Multimedia content classification and retrieval are indispensable tools in the current convergence of audiovisual entertainment and information media. Thanks to the development of broadband networks, every consumer will have digital video programmes available on-line as well as through the traditional distribution channels. In this scenario, since the early {\textquoteright}90s, the most important TV broadcasters in Europe have started projects whose aim was to achieve preservation, restoration and automatic documentation of their audiovisual archives, In particular, the association of low-level multimedia features to knowledge and semantics for the purpose of automatic classification of multimedia archives is currently the target of many researchers in both academic and IT industrial communities, This paper describes our research direction, which is focusing on three points: (a) We first introduce a new taxonomy for classification of broadcast digital archives based on a novel theoretical approach. The advantage of this taxonomy is that it can provide an unambiguous representation of multi-media informative content from the relevant points of view to the broadcasters community.

So, suitable compression techniques, which are space efficient for disk based storage, are required. This paper has provided a two level compression technique. In the first level, the structural properties of a graph are studied and strongly connected components are fused to reduce the original graph to a DAG. Paths on this DAG are then stored efficiently using a Path Normalization technique. Space complexity expressions indicate the efficiency of the method.

Quality of service (QoS) routing plays a prominent role for providing QoS in mobile wireless ad hoc networks. Real time and multimedia applications need stringent QoS requirements. Providing a complete quality-of-service (QoS) solution for the ad hoc networking environment requires the interaction and co-operation of several components which include a QoS routing protocol, a resource reservation mechanism and a QoS capable medium access control (MAC) layer. The tasks of QoS routing are in general selecting routes with satisfied QoS requirement(s), and achieving global efficiency in terms of resource utilization. QoS is more difficult to guarantee in mobile ad hoc networks than in other type of networks due to the sharing of wireless bandwidth among adjacent nodes, its dynamic topology and generally imprecise network state information.

Through such a tight integration of the motion blobs and color patches, as well as the global optimization of object trajectories, we have accomplished not only robust and efficient multi-object tracking, but also the ability to deal with merging/splitting of objects, irregular object motions, changing appearances, etc. which are the challenging problems for the most traditional tracking methods.

While LSI works on the whole collection, another procedure of feature extraction (and thus dimension reduction) exists, using binary factorization.
