We propose a generative model based on latent Dirichlet allocation for mining distinct topics in document collections by integrating the temporal ordering of documents into the generative process. The document collection is divided into time segments where the discovered topics in each segment is propagated to influence the topic discovery in the subsequent time segments. We conduct experiments on the collection of academic papers from Cite Seer repository. We augment the text corpus with the addition of user queries and tags and integrate the citation graph to boost the weight of the topical terms. The experiment results show that segmented topic model can effectively detect distinct topics and their evolution over time.

Verification and transformation of complex and uncertain conceptual schemas Yazıcı, Adnan (World Scientific Pub Co Pte Lt, 1997-12-01) In database environment it is necessary to represent complex and uncertain information at conceptual level and then transform the conceptual schema into the logical one for ultimate implementation. It is also important to verify the conceptual schema with respect to the constraints imposed on the schema definition. In this paper we primarily focus on the verification and transformation of the conceptual schema For the purpose of verification of the conceptual schema represented by the ExIFO data model (the ...
A study on enterprise resource planning systems and embedding them into the company processes Gencel, Orhan; Şen, Tayyar; Department of Information Systems (2003) In this thesis, implementations of Enterprise Resource Planning Systems are studied with a broader view. Pre-implementation preparations and post-implementation developments play key roles in the success of the ERP utilization of the companies. To find out how the success can be achieved, various concepts in ERP implementation are analyzed. Using analogies with the basic software development models, common application methodologies are studied. The study is completed with the analysis of an interesting and ...
Comparison of feature-based and image registration-based retrieval of image data using multidimensional data access methods Arslan, Serdar; Yazıcı, Adnan; Sacan, Ahmet; Toroslu, İsmail Hakkı; Acar, Esra (Elsevier BV, 2013-07-01) In information retrieval, efficient similarity search in multimedia collections is a critical task In this paper, we present a rigorous comparison of three different approaches to the image retrieval problem, including cluster-based indexing, distance-based indexing, and multidimensional scaling methods. The time and accuracy trade-offs for each of these methods are demonstrated on three different image data sets. Similarity of images is obtained either by a feature-based similarity measure using four MPEG-...
A method for concurrency control in distributed DBMSs: Permission Test Method Halıcı, Uğur (Association for Computing Machinery (ACM), 1987-01-09) In this paper, a method for concurrency control in distributed DBMSs, called Permission Test Method is proposed. The PT method satisfies the basic requirements for concurrency control, that is, it executes the transactions in a serializable order, deadlocks do not appear and indefinite postponment is prevented by the method. In PT method, transactions, which are permitted to run, are not aborted unless a related site failure occurs. Furthermore, the complexity analysis indicates that the algorithm will work...
Constructing linear unequal error protection codes from algebraic curves Özbudak, Ferruh (Institute of Electrical and Electronics Engineers (IEEE), 2003-06-01) We show that the concept of "generalized algebraic geometry codes" which was recently introduced by Xing, Niederreiter, and Lam gives a natural framework for constructing linear unequal error protection codes.
