The Influence of Feature Representation of Text on the Performance of Document Classification

no code implementations5 Jul 2017 Sanda Martinčić-Ipšić, Tanja Miličić, Ljupčo Todorovski

In this study, we measure the performance of the document classifiers trained using the method of random forests for features generated the three models and their variants.

Multilayer Network of Language: a Unified Framework for Structural Analysis of Linguistic Subsystems

no code implementations30 Jul 2015 Domagoj Margan, Ana Meštrović, Sanda Martinčić-Ipšić

The multilayer network of language is a unified framework for modeling linguistic subsystems and their structural properties enabling the exploration of their mutual interactions.

Network Motifs Analysis of Croatian Literature

no code implementations18 Nov 2014 Hana Rizvić, Sanda Martinčić-Ipšić, Ana Meštrović

Firstly, we show that the triad significance profile for the Croatian language is very similar with the other languages and all the networks belong to the same family of networks.

Toward Selectivity Based Keyword Extraction for Croatian News

no code implementations17 Jul 2014 Slobodan Beliga, Ana Meštrović, Sanda Martinčić-Ipšić

Obtained sets are evaluated on a manually annotated keywords: for the set of extracted keyword candidates average F1 score is 24, 63%, and average F2 score is 21, 19%; for the exacted words-tuples candidates average F1 score is 25, 9% and average F2 score is 24, 47%.

Preliminary Report on the Structure of Croatian Linguistic Co-occurrence Networks

no code implementations17 May 2014 Domagoj Margan, Sanda Martinčić-Ipšić, Ana Meštrović

Finally, since the size of texts is reflected in the network properties, our results suggest that the corpus influence can be reduced by increasing the co-occurrence window size.

no code implementations15 May 2014 Domagoj Margan, Ana Meštrović, Sanda Martinčić-Ipšić

Additionally, in the first shuffling approach we preserved the sentence structure of the text and the number of words per sentence.

Comparison of the language networks from literature and blogs

no code implementations12 May 2014 Sabina Šišović, Sanda Martinčić-Ipšić, Ana Meštrović
