This paper describes our joint participation in the TREC 2012 KBA task. The system is broken down as follows : first name variations of the entity topics are searched then documents containing at least one of them are retrieved. Finally documents go through two classifiers to categorize them as garbage, neutrals, relevant or centrals. This system got good results (3rd of 11) however first analy...

The need to select a component among a set of possible candidates that offer similar functionality opens the need to count with objective methods that help developers in this difficult task. One necessary step is to define a set of metrics that offer useful and simple results for the component selection process. In this position paper we present a collection of software component metrics focuse...

this paper proposes an optimal transmission expansion planning (tep) which is based on determining share of each line in merchandizing surplus (ms) of system, determining by independent system operator (iso). the more share of a line in ms of system denotes the priority of a line for expansion. the procedure of determining ms of each line in a power system is based on determining the ms share o...

Ontologies reflect our view of what exists and developing ontologies for a given domain requires a common context. This context can be characterized explicitly by means of an upper ontology. Upper ontologies define top-level concepts such as physical objects, activities, mereological and topological relations from which more specific classes and relations can be defined. As an effort to support...

This paper describes the development of a memory-based lemmatiser for Afrikaans called Lia. The paper commences with a brief overview of Afrikaans lemmatisation and it is indicated that lemmatisation is seen as a simplified process of morphological analysis within the context of this paper. This overview is followed by an introduction to memory-based learning – the machine learning technique th...
