Abstracting concepts from text documents by using an ontology
P. 20–31.
A method for computationally visualizing and interpreting a text or corpus of texts in a
taxonomy of the field is described. The method involves such stages as matching taxonomy
topics and text(s) by using annotated suffix trees (ASTs), combining multiple information such
as text abstracts, key-words and taxonomy cross-references, building clusters of taxonomy topics
and their profiles, and lifting the profiles to higher ranks of the taxonomy hierarchy.

Meloscaphander grandis is a little-known species missing from databases and papers on taxonomic revision and phylogenetic analysis of Scaphandridae. This species is redescribed herein, based on the type specimen and specimens from the abyssal plain adjacent to the Kuril-Kamchatka Trench. A phylogenetic analysis of COI, 16S, and 28S markers show M. grandis to nest within ...

Our study focuses on the distribution and diversity of different cephalaspidean species collected from the Kuril-Kamchatka Trench (KKT) during the deep-sea expeditions KuramBioI (2012), SokhoBio (2015) and KuramBioII (2016). Our study recovered several undescribed taxa from different parts of the KKT and the adjacent abyssal plain, belonging to four families: Cylichnidae s. l., Scaphandridae, Aglajidae ...

Onuphid polychaetes are tubicolous marine worms commonly reported worldwide from intertidal areas to hadal depths. They often dominate in benthic communities and have economic importance in aquaculture and recreational fishing. Here we report the phylogeny of the family Onuphidae based on the combined analyses of nuclear (18S rDNA) and mitochondrial (16S rDNA) genes. Results of ...

Species of the genus Dendronotus are among the most common nudibranchs in the northern Hemisphere. However, their distribution and composition in the North-west Pacific remain poorly explored. In the present study, we observed Dendronotus composition in northwestern part of the Sea of Japan, using an integrative approach, included morphological and molecular phylogenetic analyses and molecular ...

Being an unsupervised machine learning and data mining technique, biclustering and its multimodal extensions are becoming popular tools for analysing object-attribute data in different domains. Apart from conventional clustering techniques, biclustering is searching for homogeneous groups of objects while keeping their common description, e.g., in binary setting, their shared attributes. In bioinformatics, biclustering is used ...

The taxonomy of common northern nudibranch molluscs of the genus Dendronotus in the vast cold regions of Eurasia remains largely unknown. Abundant material collected in many localities from the Barents Sea, via the Arctic region, to the north-west Pacific was analysed for the first time. An integrated approach combining morphological and ontogenetic data with molecular ...

A two-step approach to taxonomy construction is presented. On the first step the frame of taxonomy is built manually according to some representative educational materials. On the second step, the frame is refined using the Wikipedia category tree and articles. Since the structure of Wikipedia is rather noisy, a procedure to clear the Wikipedia category ...

Given $m$ documents of total length $n$, we consider the problem of finding a longest string common to at least $d \geq 2$ of the documents. This problem is known as the \emph{longest common substring (LCS) problem} and has a classic $\Oh(n)$ space and $\Oh(n)$ time solution (Weiner [FOCS'73], Hui [CPM'92]). However, the use of ...

This paper offers an outline of the perception of “transnational employment relations”[1] in a legal context. It will analyse various doctrinal and legislative approaches to the definition of the phenomenon, as well as the usage of the terms employed in its naming, its key characteristics and classifications. The author will reveal and explore the reasons ...

Abstract. A suffix-tree based method for measuring similarity of a key phrase to an unstructured text is proposed. The measure involves less computation and it does not depend on the length of the text or the key phrase. This applies to the following tasks in semantic text analysis:
Finding interrelations between key phrases over a set ...

Any company consists of business processes, and enterprise management is actually performed by managing them. Every process requires proper information support and cannot be managed successfully without it, hence neither can the whole company. However creating such support system is quite a serious problem. Content analysis based on corporative taxonomies use is a simple but ...
