The paper reports on the methodology and final results of a large-scale synset mapping between plWordNet and Princeton WordNet. Dedicated manual and semi-automatic mapping procedures as well as interlingual relation types for nouns, verbs, adjectives and adverbs are described. The statistics of all types of interlingual relations are also provided.
Supervised approaches usually achieve the best performance in the Word Sense Disambiguation problem. However, the unavailability of large sense annotated corpora for many low-resource languages make these approaches inapplicable for them in practice.
In this paper, we mitigate this issue for the Persian language by proposing a fully automatic approach for obtaining Persian SemCor (PerSemCor), as a Persian Bag-of-Word (BoW) sense-annotated corpus. We evaluated PerSemCor both intrinsically and extrinsically and showed that it can be effectively used as training sets for Persian supervised WSD systems. To encourage future research on Persian Word Sense Disambiguation, we release the PerSemCor in http://nlp.sbu.ac.ir.
The purpose of this study, is to explain the factors that may be able to affect the
prices of stocks in the IPO. So it could be priced at it's fair price, not less or more than it.
Which caused by the existence of asymmetric information between the
investors in the
financial market. Whereas, the asymmetric information generates adverse selection with
the investors, about the real values of the company and it's stocks in the IPO market.
This research aims to study the multiple signals, which could be used by the firm to
reduce the asymmetric information and highlight the real value of the firm and it's quality,
in Damascus Securities Exchange between (2009-2011). Some of these signals, which has
been considered in this research are: the standards of Financial and Non Financial
disclosure in it's prospectus.
The researcher reached to several results:
The Financial disclosure standards has no relation to the stock price in the Syrian
IPO market, and cannot be used as a signal to show the real value of the firm. On the other
hand Non-Financial disclosure standards could be used as a good signal to show the real
and fair price of the firms and their stocks in the IPO process.
This result could help the financial market and the firms who want to go public to
use this factors as a signal about it's quality, and for reduce the under pricing in their IPOs.
The mass spectra of 5 trisubstituted aromatic compounds were studied. The
spectra were recorded by local GC-MS at 70 eV and compared with
bibliographic spectra. The spectra of each compound were different. The using
of local GC-MS for identificati
on required recording the spectra references at
the same conditions.
