2. 1. Finding, extracting and exploiting structure in text and hypertext

   Author : Ola Ågren; Jürgen Börstler; Frank Drewes; Maarten de Rijke; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Automatic propagation; CHiC; Data mining; Discrete data; Extraction; Hierarchies; ProT; Rank distribution; S²ProT; Spatial linking; Web mining; Web searching; Computer science; Datalogi; business data processing; administrativ databehandling;

   Abstract : Data mining is a fast-developing field of study, using computations to either predict or describe large amounts of data. The increase in data produced each year goes hand in hand with this, requiring algorithms that are more and more efficient in order to find interesting information within a given time. READ MORE

4. 2. Subject retrieval in web-based library catalogs

   Author : Koraljka Golub; Jadranka Lasić-Lazić; Department of Information Science Filozofski fakultet u Zagrebu; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; British university libraries; Croatian university libraries; Indexing and retrieval systems; Online library catalogs; Subject access points; Subject retrieval; User interface; User search behavior; WebPACs; Library and Information Science; Biblioteks- och informationsvetenskap;

   Abstract : This thesis has been motivated by past research, problems and realizations that online library catalog users frequently perform subject searches – using keywords, subject headings and descriptors – and these searches have yielded unsatisfactory results. Web-based catalogs or WebPACs (Web-based Online Public Access Catalogs), belonging to the so-called third generation of online catalogs and providing a wide variety of search options, remain largely underutilized despite the continuous advancement of information retrieval systems.

5. 3. Querying mediated web services

   Author : Manivasakan Sabesan; Tore Risch; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Abstract : Web services provide a framework for data interchange between applications by incorporating standards such as XMLSchema, WSDL, SOAP, HTTP etc. They define operations to be invoked over a network to perform the actions. These operations are described publicly in a WSDL document with the data types of their argument and result. READ MORE

6. 4. Automated subject classification of textual web pages, for browsing

   Author : Koraljka Golub; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automated classification; subject browsing; structural Web-page elements; Web page classification; document clustering; bibliographic coupling; text categorization; Subject classification;

   Abstract : With the exponential growth of the World Wide Web, automated subject classification of Web pages has become a major research issue in information and computer sciences. Organizing Web pages into a hierarchical structure for subject browsing is gaining more recognition as an important tool in information-seeking processes. READ MORE

7. 5. Towards Automation in Digital Investigations : Seeking Efficiency in Digital Forensics in Mobile and Cloud Environments

   Author : Irvin Homem; Theo Kanter; Panagiotis Papapetrou; Rahim Rahmani; Fredrik Björck; Stockholms universitet; []
