Local search engine with global content based on domain specific knowledge

In the growing need for information we have come to rely on search engines. The use of large scale search engines, such as Google, is as common as surfingthe World Wide Web. We are impressed with the capabilities of these search engines but still there is a need for improvment. A common problem withsearching is the ambiguity of words. Their meaning often depends on the context in which they are used or varies across specific domains. To resolve this we propose a domain specific search engine that is globally oriented. We intend to provide content classification according to the target domain concepts, access to privileged information, personalization and custom rankingfunctions. Domain specific concepts have been formalized in the form ofontology. The paper describes our approach to a centralized search service for domain specific content. The approach uses automated indexing for various content sources that can be found in the form of a relational database, we! b service, web portal or page, various document formats and other structured or unstructured data. The gathered data is tagged with various approaches and classified against the domain classification. The indexed data is accessible through a highly optimized and personalized search service

Application of semantic technology for calculation of welding time in the development of new products

Određivanju vremena izvršenja je vrlo važno u ranim fazama svakog projekta (npr. ponude, dizajn faza, itd.), a posebno u fazi planiranja. Ovaj rad predstavlja naš pristup procjeni vremena zavarivanja u svrhu planiranja proizvodnog procesa. Pristup se temelji na znanju stručnjaka za zavarivanje iz društva Nieros metala d.o.o. i na standardu za zavarivanje (međunarodni i unutarnji). Ekspertni sustav je razvijen na temelju semantičkih tehnologija za izračunavanje vremena zavarivanja u fazi projektiranja proizvoda. Sistem je snažno integriran sa glavnim ERP sustavom društva Nieros metala d.o.o. Rezultati eksperimenta su prikazani na kraju ovog članka.Determining the time of execution is very important in the early stages of each project (e.g. making offers, design phase etc.), especially in the stage of planning. This paper presents our approach to estimating the welding time for the purposes of planning the manufacturing processes. The approach is based on the knowledge of welding experts from the Nieros metal d.o.o. company and standards of welding (international and internal). An expert system was developed based on semantic web technologies for calculating the welding time in the product design phase and it is strongly integrated with the main ERP system of the Nieros metal d.o.o. company. Test results are presented at the end of this article

Searching for information on horizontally distributed sources

Uporaba spletnih iskalnikov je postala vsakodnevna stalnica. Pogosto so spletni iskalniki edini način iskanja informacij. Spletnim mestom, ki želijo svojim uporabnikom ponuditi napredne iskalne storitve, pogosto ne zadostuje uporaba storitev večjih iskalnikov (Google, Yahoo, Live Search). Razlogi za izgradnjo lastnih iskalnih storitev so predvsem v varnosti, želeni ravni poosebitve ter seveda v potrebi po prilagojenem ocenjevanju in razvrščanju rezultatov. Prispevek predstavi delovanje sodobnih iskalnikov in podrobneje opiše iskalno storitev, ki je bila razvita z vidika posameznega spletnega mesta. Iskalni zadetki se avtomatsko prilagajajo uporabniku in njegovim pravicam, ponujeno pa je tudi iskanje po sorodnih spletnih mestih ter strukturiranih in nestrukturiranih virih podatkov. Iskalna storitev ponuja prav tako poosebljanje iskalnih rezultatov glede na interesna področja uporabnika.In the modern society the use of online search engines is a daily routine. More often than not it is the only way of getting the desired information instantly. For a large web portal, with the ambition to provide their users with advanced search services, the feature specifications of the search services they require far exceed the capabilities provided by large search engines (Google, Yahoo, Live Search). The main initiative for a custom search service is the need for security and authorized access to certain contentalso the desired personalization level and a customized ranking of search results are both major contributors. The paper reviews the architecture of modern search engines and presents in greater detail the search service that was developed. The service provides automated use of users\u27 credentials to limit the search results to only the content that the user has been granted access to, it provides centralized search capability across multiple web siteswith similar content as well as structured and unstructured data sources.The search service also provides personalization according to the user\u27s field of interest

Using Intelligent Search for Finding Medical Sites

In this paper we present the intelligent search tool, which we developed in order to automate search and evaluation of Web sites. We used TFIDF heuristics to determine term frequency and decision trees to evaluate the quality of sites. Training set for the decision tree contained manually evaluated Web sites. Each Web site was described by the combination of various attributes, complexity metrics and the evaluation. The intelligent search tool is equipped with the userfriendly interface, which enables people to exploit the tool to its limits with minimum effort, in their quest for the information. For testing purposes, we looked for sites with telemedical content. The set of sites, which was the result of using intelligent search tool has been evaluated by a group of students.

Podgorelec V., Integration of Complexity Metrics With the Use of Decision Trees, Software engineering notes

Abstract. We would like to present the use of the decision tree approach in the integration of various complexity metrics on the example of distinguishing between random and ordinary programs. Following our proposition that randomness indicates meaningless we can state that with the approach we are able to measure the »meaning « of computer programs. The main contributions stated in the paper is that the new way of metrics integration enabling one to combine metrics with various measurement units. 1
