Given a large hierarchical concept dictionary (thesaurus, or ontology), the task of selection of the concepts that describe the contents of a given document is considered. A statistical method of document indexing driven by such a dictionary is proposed. The method is insensible to inaccuracies in the dictionary, which allow for semiautomatic translation of the hierarchy into different language...

This document reviews the security threats associated with: o the marking of signalling messages to indicate that they are related to an emergency; and o the process of mapping from locations to Universal Resource Identifiers (URIs) pointing to Public Safety Answering Points (PSAPs). This mapping occurs as part of the process of routing emergency calls through the IP network. Based on the ident...

•Mathematics plays a fundamental role in Science, Technology, and Engineering (learn from Math, apply for STEM) •Mathematical knowledge is rich in content, sophisticated in structure, and technical in presentation! •There is a lot of documents with maths – 120.000 journal articles per year in pure/applied math, 3.5 Million overall – 50 million science articles in 2010 with a doubling time of 8-...

Developments in text retrieval on the AP1000 since last year's PCW are reported. The software, now called PADRE, has been entered in the competition associated with the 1994 Text Retrieval Conference (TREC-3). PADRE is now capable of document relevance estimation and ranking, and supports data loading from and dumping to the Fujitsu Local Filesystem. A new load balancing operation has been devi...

Publishing is a distributed process which is characterized by the cooperation of different experts. The approach of the Integrated Publication and Information Systems Institute (IPSI) to support electronic publishing is to build an integrated publication environment. The publication of electronic documents demands enhanced support from publishing tools and imposes new challenges on database tec...

We discuss the task of selection of the concepts that describe the contents of a given document. We propose to use a large hierarchical concept dictionary (thesaurus) for this task. A statistical method of document indexing driven by such a dictionary is proposed. The problem of handling non-terminal nodes in the hierarchy is discussed. Common sense-complaint methods of automatically assigning ...

Electronic Data Interchange (EDI) consists in the interchange of structured and standardized data between computers belonging to parties involved in a business relationship. The potential of EDI has been recognized since the mid-70’s when the dematerialization and the automation of document transmission and handling was identified as a source of major time and money savings. Indeed the transmis...
