When non-unique values are used as the identifier of entities, due to their homonym, confusion can occur. In particular, when (part of) “names” of entities are used as their identifier, the problem is often referred to as the name disambiguation problem, where goal is to sort out the erroneous entities due to name homonyms (e.g., if only last name is used as the identifier, one cannot distingui...

Fourteen species (twelve adult and two larval) of nematodes belonging to the Ascaridoidea, Camallanoidea, Cosmocercoidea, Habronematoidea, Oxyuroidea, Seuratoidea and Trichinelloidea were collected from fishes in the Sudan (River Nile and Atbara Dam Lake), whereas only four species (one adult and three larval) of the Ascaridoidea, Camallanoidea, Dioctophymatoidea and Trichinelloideafrom fishes ...

The large polychaete genus Polycirrus (Terebellida: Polycirridae) is revised based on a morphological study of the type material of most of the approximately 74 nominal species; 59 species, including a new species, P. coibensis n.sp., from the Pacific coast of Panama, are accepted as valid. All characters are reanalysed and discussed in the light of recent phylogenetic studies of terebellomorph...

It is shown that a total of eight pre-existing genus-group names in Diptera were "borrowed" and deliberately given new identities in the systematic works of J.C. Fabricius: Bibio Fabricius, 1775, Ceria Fabricius, 1794, Hirtea Fabricius, 1798, Mulio Fabricius, 1798, Scatophaga Fabricius, 1805, Sicus Fabricius, 1798, Thereva Fabricius, 1798 and Voluccella Fabricius, 1794. These names are reviewed...

This paper describes the participation of the REINA research group at CLEF 2009 Robust-WSD Task. We have participated in both monolingual and bilingual subtasks. In past editions of the robust task our research group obtained very good results for non-WSD experiments applying local query expansion using co-occurrence based thesauri constructed using windows of terms. We applied it again. For WS...

The correct generic name for the species that belong to Eucharia Boisduval, 1870, a homonym, is either Annamaria D’Abrera & Bálint, 2001, which has been considered to be unavailable, or Lamasina Robbins, 2002, a replacement name for Eucharia. A recent re-interpretation of the original description of Annamaria was incorrect, and Annamaria is confirmed as being unavailable under Article 13.1 of t...

Recently, LSI (Latent Semantic Indexing) based on SVD (Singular Value Decomposition) is proposed to overcome the problems of polysemy and homonym in traditional lexical matching. However, it is usually criticized as with low discriminative power for representing documents although it has been validated as with good representative quality. In this paper, SVD on clusters is proposed to improve th...

The problem of estimating the latent states of a dynamical system from observed data often arises in many branches of physical and social sciences, including image processing, navigation, econometrics, finance and meteorology. Filtering refers to any method for obtaining such state estimates, recursively in time, by combining model predictions with noisy observations. While the solution to the ...

Southern Switzerland has a long tradition of chestnut cultivation as a staple food. Local inhabitants constantly selected varieties according to the ripening period, the type of use, and the adaptability to the territory. As a result, the panorama of chestnut varieties is very complex, as reflected by more than 120 different variety names in an area of 26,000 ha. Since 1994, 47 varieties have b...

Material of the paederine genus Lathrobium Gravenhorst, 1802 from the Chinese provinces Heilongjiang, Ningxia, Qinghai, Henan, Anhui, Zhejiang, Jiangxi, Hunan, Chongqing, Guizhou, Yunnan and Guangdong was examined. Twenty-one species were identified, seventeen of which are described as new: L. liuae (Heilongjiang: Hongwei); L. ningxiaense sp. n. (Ningxia: Heshangpu); L. baiyunense sp. n. (Henan...
