Systems label the arguments of given target verbs with roles. The training data is the Wall Street Journal sections 02 to 21 with full syntactic parses from two parsers, and the test is section 23 plus three Brown sections (ck01 to 03) to test robustness… 2. **[Simple Semi-supervised Dependency Parsing](https://md.research.elamur.ai/free/en/papers/koo-2008-simple-semi-supervised-dependency-parsing/)** *(2008 · 655 citations)* Word-to-word statistics help resolve attachment ambiguities in parsing, but they are too sparse to estimate reliably from treebanks alone. 3. **[Experiments with a Higher-Order Projective Dependency Parser](https://md.research.elamur.ai/free/en/papers/carreras-2007-experiments-higher-order-projective-dependency/)** *(2007 · 358 citations)* The paper asks whether a graph-based projective dependency parser becomes more accurate when each scored factor includes more of the surrounding tree than a single arc, or a single arc plus a sibling. Carreras defines a factor as one labeled head–modifier dependency together with three nearby unlabeled arcs: 4. **[FreeLing: An Open-Source Suite of Language Analyzers](https://md.research.elamur.ai/free/en/papers/carreras-2004-freeling-open-source-suite-language/)** *(2004 · 325 citations)* Most NLP applications, such as machine translation, summarization and dialogue systems, depend on basic analysis steps like tokenization, morphology, lemmatization and PoS tagging. 5. **[Prepositional Phrase Attachment over Word Embedding Products](https://md.research.elamur.ai/free/en/papers/lingbulk-2017-madhyastha-prepositional-phrase-attachment-over-word/)** *(2017 · 1 citation)* The paper scores a PP attachment with a tensor product of the word vectors of the verb, the noun, the preposition and the object, with a low-rank constraint on the tensor. ## Also in our library 4 more works of theirs are in our library without a page here yet; they will appear as we publish them. ## Co-authors here 5 co-authors with a page, the most papers together first. - [Lluís Màrquez](https://md.research.elamur.ai/free/en/authors/lluis-marquez/) - [Lluís Padró](https://md.research.elamur.ai/free/en/authors/lluis-padro/) - [Michael Collins](https://md.research.elamur.ai/free/en/authors/michael-collins/) - [Pranava Madhyastha](https://md.research.elamur.ai/free/en/authors/pranava-madhyastha/) - [Terry Koo](https://md.research.elamur.ai/free/en/authors/terry-koo/) ## Cited by Papers of our library cite their works 801 times (of the 140 884 papers whose bibliographies we read); [72 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/xavier-carreras/cited-by/).
