Bootstrapping the Albanian Information Retrieval

Nikitas N. Karanikolas
2009 2009 Fourth Balkan Conference in Informatics  
Keywords -information retrieval; stemming algorithm; stopword list I.  ...  As a consequence of our study (investigation) we provide a naive-single-step (rudimentary) stemming algorithm for the Albanian language. A stopword list is also created.  ...  Without their help, this work would still be in my mind.  ...

An Efficient Mechanism for Stemming and Tagging: The Case of Greek Language [chapter]

Giorgos Adam, Konstantinos Asimakis, Christos Bouras, Vassilis Poulopoulos
2010 Lecture Notes in Computer Science  
Our system is constructed in such a way that can be easily adapted to any existing system and support it with recognition and analysis of Greek words.  ...  In an era that, searching the WWW for information becomes a tedious task, it is obvious that mainly search engines and other data mining mechanisms need to be enhanced with characteristics such as NLP  ...  A Greek search engine that was constructed recently does utilize a stemmer; though, no information is publicly available except for a reference to the complete work that was done for the specific search  ...

Boosting Venue Page Rankings for Contextual Retrieval-Georgetown at TREC 2013 Contextual Suggestion Track

Jiyun Luo, Hui Yang
2013 Text Retrieval Conference  
Since the Open Web is not used in our submissions, the task is essentially a retrieval task instead of a result merging task.  ...  Ideal relevant documents for this task should be a list of Web pages each of which is a venue's homepage, which we call a "venue page".  ...  It was essentially a result merging task that utilizes a personalized learning to rank framework to merge top returned results from existing commercial search engines such as Google Place and Yelp.  ...
