The total output value of the construction industry, a pillar industry of China, is continuously growing with the expansion of the production and operation scale of Chinese construction enterprises. The extensive high-input mode has promoted the economic growth of the construction industry. Despite the fruitful and outstanding results, production inefficiency has become especially prominent. Though developing rapidly, China{\textquoteright}s construction industry possesses fewer ecological investments, accompanied by low environmental awareness and little importance to environmental protection, constantly failing to eliminate high energy consumption, high investments, and high emissions. In addition, the contradiction between the economic growth of the construction industry and the ecological environment remains evident. In this paper, the production efficiency of China{\textquoteright}s construction industry was transversely and longitudinally measured using the DEA-Malmquist index method, followed by a further analysis of the factors influencing the production efficiency of China{\textquoteright}s construction industry based on the Tobit regression model. The results show that the average production efficiency of China{\textquoteright}s construction industry is the highest in the East, moderate in the West, and lowest in the centre. The number of construction enterprises, per capita capital, industrial structure, the proportion of state-owned capitals, and GDP are significant at 1\%, 10\%, 1\%, 1\%, and 1\%, respectively. The research results can provide theoretical reference for reasonably establishing an ecological efficiency evaluation system for the construction industry to analyze the differences in environmental efficiency among different provinces and regions, further find out the key factors influencing ecological efficiency, propose the corresponding pertinent policy suggestions, and ultimately improve the ecological efficiency of China{\textquoteright}s construction industry.

:Predicting stock price movements has been challenging yet crucial for investors and financial ana- lysts. Fluctuations in stock prices are valuable economic indicators, providing insights into overall economic well- being, consumer confidence, and market sentiment. In this study, we evaluate the efficacy of three different ma- chine and deep learning algorithms in anticipating stock price trends. We assess the performance of Logistic Re- gression, Random Forest Regression, and Long Short- Term Memory (LSTM) algorithms in forecasting whether a stock{\textquoteright}s price will rise or fall in the upcoming period, utilising historical stock price data as input features. Our findings demonstrate that while each algorithm exhibits varying degrees of predictive accuracy, LSTM networks stand out as they generally outperform Logistic Regression and Random Forest Regression in capturing the complex tem- poral dependencies inherent in stock price data. This suggests that LSTM networks, with their superior perfor- mance, hold significant promise as effective tools for stock price trend prediction, particularly in volatile and non-lin- ear financial markets. This could be a game-changer in stock price prediction, instilling optimism about the fu- ture of stock market analysis..

\ In the last recent years, the customer reviews has attracted an increasing interest by researchers and companies thanks to the advancement in E commerce and business applications. The ability to successfully decide whether a review will be helpful to other customers and thus give the product more exposure is vital to companies that support these reviews, companies like Google, Amazon and Yelp! The problem is that some customers are giving rating in conflict with their comments obliging other reviewers to read the comments to understand the reason of this contradiction. Sentiment analysis is the process of automatically identifying opinions expressed in text on certain subjects. The accuracy of sentiment analysis has a direct effect on decision making in both business and government. Also, recommender system is one of the hot topics in the field of big data, especially with the development and growth of the World Wide Web.

\ In developing cities such as in Jakarta, there are a lot of vehicle parking locations that still use conventional methods, which can harm drivers and also parking area owners alike, the process is slow and unsafe, making many people around feel afraid to use parking locations that are still conventional, the conventional parking lots in Jakarta is too many, sometimes also make people have no other choice but to use unsecured parking lots, theft is the main factor that is difficult to avoid, especially in developing countries like Indonesia, which are not safe, and the location of the parking lot that is very open, makes a lot of opportunities which of course can be used by thieves or irresponsible people. Not only thieves, drivers who do not want to pay for parking, are also a problem for owners of parking lots. With the problems of these users, we plan to make modular parking applications that can be installed easily and cheaply, but because our group is not so large, there are several challenges that we face, such as time and requirements that can increase later, with thus we plan to make this parking application using the Extreme Programming method, which is possible and very suitable for the problems that our group is facing. The use of Extreme Programming turned out to be very helpful, and can also produce an application that matches the existing user stories.

The numerical analysis presented in this paper may help in studying the affect of some parameters on the system performance and stability.}, keywords = {Hybrid network, Network, Performance, PRMA, Token ring, Wireless, Words}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-49149110443\&partnerID=40\&md5=461f26224ae3a230d93b0fcefcafdf1d}, author = {Al-Amawi, A. and Khanfar, K.} } @article {101, title = {Personalized searching by learning wordnet-based user profiles}, journal = {Journal of Digital Information Management}, volume = {5}, year = {2007}, note = {Cited By (since 1996):2Export Date: 10 July 2014}, month = {2007}, pages = {309 - 322}, abstract = {The amount of information available on the Web and in Digital Libraries is increasing over time. In this context, the role of user modeling and personalized information access is becoming crucial: Users need a personalized support in sifting through large amounts of retrieved information according to their interests. Information filtering and retrieval systems relying on this idea adapt their behavior to individual users by learning their preferences during the interaction in order to construct a profile of the user that can be later exploited in the search process. We propose a novel technique to learn user profiles which exploits word sense disambiguation based on the WordNet lexical database, in an attempt to produce semantic user profiles that might discover topics semantically closer to the user interests. Semantic profiles are used in the definition of a retrieval model that turns the traditional document-query search paradigm into a novel document-query-profile paradigm. As an example of this paradigm, we present an extension of the vector space model in which profiles are used to modify the ranking of search results obtained in response to a query, hopefully putting personally relevant items on the top of the result list. Experimental results in a movie retrieval scenario indicate that the proposed model to personalize Web search is effective.}, keywords = {Machine learning, Personalization and information filtering, User modeling, WordNet}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-66149191527\&partnerID=40\&md5=750d800edd5f7fe76d849dd465dafff9}, author = {Semeraro, G.} } @article {102, title = {Pre-processing and Path Normalization of a web graph used as a social network}, journal = {Journal of Digital Information Management}, volume = {5}, year = {2007}, note = {Cited By (since 1996):2Export Date: 10 July 2014}, month = {2007}, pages = {262 - 276}, abstract = {Many efforts have been made for compression of web graphs. Most of these methods are suitable for search engines and are centered around encoding links and URLs efficiently. The purpose is to handle a large set of web pages in the main memory against any web based search. The authors of the present paper are interested in studying web graph as a social network and to develop a data model for it. 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. Relevant operators required for accessing the original graph through the compressed representations have also been discussed. Important earlier works have been referred to indicate the requirements of the present approach.}, keywords = {Compression technique, Path normailisation technique, Social software, Web search}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-57949092373\&partnerID=40\&md5=08a3428b63ad14c630820944a0e9c222}, author = {Teja, C.B. and Mitra, S. and Bagchi, A. and Bandyopadhyay, A.K.} } @article {95, title = {Promotion of local to global operation in train control system}, journal = {Journal of Digital Information Management}, volume = {5}, year = {2007}, note = {Cited By (since 1996):15Export Date: 10 July 2014}, month = {2007}, pages = {231 - 236}, abstract = {Railway interlocking system is a safety critical system.

In this paper, parallel algorithms to solve the generalized fully and partially instantiated forms of the same generation query in deductive databases are presented. The algorithms use special data structures, namely, a special matrix that stores paths from source nodes of the graph representing a two-attribute normalized database relation to all nodes reachable from these source nodes, and a reverse matrix that stores paths from any node to all source nodes related to that node.}, keywords = {Deductive databases, Linear recursive rules, Parallel databases, Same generation query}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33749424147\&partnerID=40\&md5=f02aca3cb9370bdc7720ce48f7507278}, author = {Arman, N.} } @article {50, title = {Peer-to-peer content search supported by a distributed index in a publication/search model}, journal = {Journal of Digital Information Management}, volume = {4}, year = {2006}, note = {Export Date: 10 July 2014}, month = {2006}, pages = {175 - 183}, abstract = {Peer to-peer networks (P2P) are considered a valid approach for the construction of distributed systems. Further research projects in the last few years have focused on using this kind of networks as an alternative for solving different situations that have traditionally required centralized servers, such as search engines. This paper deals with the problem of content search in highly distributed and dynamic environments. We propose and evaluate a distributed index model built upon a peer-to-peer network which supports complete indexing of text documents and allows searching by content. A distinctive feature of this proposal is that it requires no specific network topology or hierarchy. Evaluations with different settings were performed by simulating a 10,000-node network, where each node had the capability to share documents. With regard to the traffic generated, experiments show an improvement in efficiency of between 84\% and 93\% over similar systems like Gnutella. The evaluation of retrieval performance using a test collection showed that the P2P system was able to achieve the same level of performance as the centralized system. It was also found that the amount of traffic generated by this model varies between 80 and 225 Kb per set of query and answers.}, keywords = {Distributed index model, Nodes, P2P network evaluation, P2P networks}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33749394455\&partnerID=40\&md5=1ab83251bfe0f9c3bd58f562a6312336}, author = {Tolosa, G.H. and Peri, J.A. and Bordignon, F.R.A.} } @article {48, title = {Providing support for interaction with consistent multimedia presentations}, journal = {Journal of Digital Information Management}, volume = {4}, year = {2006}, note = {Export Date: 10 July 2014}, month = {2006}, pages = {124 - 130}, abstract = {Multimedia presentations are generally specified in terms of spatial and temporal relations between the media objects involved.

Our main contribution is the design of an algorithm which aids in resolving these consistency issues dynamically and efficiently. The other salient features of our approach are a new composite spatio-temporal operator and an effective relaxation policy.

Integrating association rule and classification also known as associative classification is a promising approach that derives classifiers highly competitive with regards to accuracy to that of traditional classification approaches such as rule induction and decision trees. However, the size of the classifiers generated by associative classification is often large and therefore pruning becomes an essential task. In this paper, we survey different rule pruning methods used by current associative classification techniques. Further, we compare the effect of three pruning methods (database coverage, pessimistic error estimation, lazy pruning) on the accuracy rate and the number of rules derived from different classification data sets. Results obtained from experimenting on different data sets from UCI data collection indicate that lazy pruning algorithms may produce slightly higher predictive classifiers than those which utilise database coverage and pessimistic error pruning methods. However, the potential use of such classifiers is limited because they are difficult to understand and maintain by the end-user.}, keywords = {Association rule, Associative classification, Classification, Data mining, Rule pruning}, url = {http://www.scopus.com/inward/record.url?eid=2-s2.0-33749400880\&partnerID=40\&md5=0633368b3744eefc60e6e205c64d95f4}, author = {Thabtah, F.} }
