| Introduction | Tagset for character-level part-of-speech tagging . |
| Representations and models | In particular, our shallow tree structure is a two-level syntactic hierarchy built from word lemmas (leaves) and part-of-speech tags that are further grouped into chunks (Fig. |
| Representations and models | As full syntactic parsers such as constituency or dependency tree parsers would significantly degrade in performance on noisy texts, e.g., Twitter or YouTube comments, we opted for shallow structures, which rely on simpler and more robust components: a part-of-speech tagger and a chunker. |
| Representations and models | Hence, we use the CMU Twitter pos-tagger (Gimpel et al., 2011; Owoputi et al., 2013) to obtain the part-of-speech tags . |
| Features | features on preterminal part-of-speech tags . |
| Introduction | An independent classification approach is actually very viable for part-of-speech tagging (Toutanova et al., 2003), but is problematic for parsing — if nothing else, parsing comes with a structural requirement that the output be a well-formed, nested tree. |
| Other Languages | These part-of-speech taggers often incorporate substantial knowledge of each language’s morphology. |
| Introduction | For instance, morphological properties are closely tied to part-of-speech tags , which in turn relate to positional features. |
| Introduction | The power of the low-rank model becomes evident in the absence of any part-of-speech tags . |
| Results | Syntactic Abstraction without POS Since our model learns a compressed representation of feature vectors, we are interested to measure its performance when part-of-speech tags are not provided (See Table 4). |
| Data and Tools | 3.3 Part-of-Speech Tagging |
| Data and Tools | As part-of-speech tags are also a form of syntactic analysis, this assumption weakens the applicability of our approach. |
| Our Approach | By reducing unaligned edges to their deleXicalized forms, we can still use those deleXicalized features, such as part-of-speech tags , for those unaligned edges, and can address problem that automatically generated word alignments include errors. |
| Approach | For example, we can map each DOM tree node onto an integer equal to the number of children, or map each entity string onto its part-of-speech tag sequence. |
| Approach | On the other hand, random words on the web page tend to have more diverse lengths and part-of-speech tags . |
| Approach | o PHRASEPOS and WORDPOS ( part-of-speech tags for whole phrases and individual words) |
