....a uni cation grammar is applied to each sentence, giving a chart as a result. The grammar is partial but gives a complete coverage of the main elements of the sentence, such as noun phrases, prepositional phrases, sentential complements and simple sentences. It can be seen as a shallow parser [2, 3] that can be used for subsequent processing. However, it contains both morphological an syntactic ambiguities, giving a huge number of di erent interpretations per sentence. After that, the resulting chart is treated as an automaton to which nite state disambiguation constraints and lters can ....

....Figure 1 shows the architecture of the system. First, the system performs morphological analysis based on two level morphology [Koskenniemi 1983; Alegria et al. 1996] and disambiguation using the Constraint Grammar formalism [Karlsson et al. 1995] As a second step, a partial parser is applied [Abney 1997], which recognizes basic syntactic units including noun phrases, prepositional phrases and several types of subordinate sentences. Currently we can employ two different partial parsers, one of them using a unification grammar [Aldezabal et al. 2000] and the other one based on the Constraint ....

....and applied in a bootstrapping manner back to the phrases extracted from the corpora in order to classify as many as possible of the words that are members of the retrieved phrases. The level of the fine grained syntactic analysis is made possible through the use of a robust parser developed by Abney (1997) in which Kokkinakis Johansson Kokkinakis (1999) have developed a large coverage grammar for written Swedish. The semantic lexicons we refer to are the Swedish SIMPLE lexicon (Semantic Information for Multifunctional Plurilingual Lexica) and gazeteers of person, location and organization names. ....

....words (e.g. Subject or Object relations) are relevant to the classification and enrichment phases. Several research works suggest that efficient and robust syntactic processing is viable through processes of decomposition of the grammatical knowledge and lexicalization (Grinberg et al. 1996) (Abney, 1996). In line with these works, the parsing component in TREVI is based on Chaos (a Chunk Oriented Analysis System, Basili et al. 1998c) a novel parsing architecture exploiting two major principles: stratification of the grammar and lexicalization. Chaos consists of a modular architecture where ....

Finite state cascaded methods have already been applied to the POS task [1]. Let us outline one possible approach.

(Chelba and Jelinek, 1998; Henderson and Lane, 1998) Unfortunately, the empiricist revolution also did not lead to the sometimes already expected breakthrough (Clark and Lutz, 1990) Stochastic approaches to part of speech tagging are still lagging behind the more conventional symbolic solutions (Abney, 1997) and 2 only in very specialised domains are trainable models able to achieve a close to competitive performance. On the other hand, corpus based techniques o er a quite attractive solution to the knowledge acquisition bottleneck from which all symbolic approaches su er. Moreover, due to their ....

A useful discussion of the relative merits of statistical and rule based approaches can be found in [1]. Those rule based taggers tend to be more compact, faster and more comprehensible. A HMM tagger has two notable advantages. Firstly, it can be trained using untagged text, although better performance is possible using tagged text. Secondly, HMM taggers can perform tagging on a ....

This feature distinguishes our approach from many other dependencybased parsing approaches (Covington 90; Sleator Temperley 93; Tapanainen Jarvinen 97) As said in (Abney 96) By reducing the sentence to chunks [i.e. nr phrases] there are fewer units whose associations must be considered, and we can have more confidence that the pairs being considered actually stand in the syntactic relation of interest, rather than being random pairs of words that happen to ....

....long or ambiguous texts well; and it is often difficult to recover from mistakes caused by incompleteness of the grammar. Partial parsing seeks to avoid these difficulties by sacrificing the goal of a complete and accurate parse. A good overview of partial parsing techniques is given by Abney[3]. By only conducting partial analyses, partial parsers are better equipped to handle a wider variety of constructions, including ungrammatical ones, typically by ignoring anything for which it does not have a good model. Many partial parsers try to recover only the core of noun phrases. Others try ....

It may suffice to use a better, more thoroughly proven noun phrase chunker from other researchers [9, 3]. The PCFG failed in some cases because of attachment decisions. Since the PCFG parser had to construct a full parse, it was forced to make decisions with inadequate information. Additionally, for the PCFG experiment, there were a number of errors that had no single obvious problem. The output of ....
