Harl. British Library, Harleian MS. Fifteenth century.

The most widespread file representation uses IOB tags. In this scheme, each token is tagged with one of three special chunk tags, I insideO outsideor B begin.

A token is tagged as B if it marks the beginning of a chunk. Subsequent tokens within the chunk are tagged I. All other tokens are tagged O. The B and I tags are suffixed with the chunk type, e.

Of course, it is not necessary to specify a chunk type for tokens that appear outside a chunk, so these are just labeled O.

An example of this scheme is shown in 2. Tag Representation of Chunk Structures IOB tags have become the standard way to represent chunk structures in files, and we will also be using this format.

Here is how the information in 2. This format permits us to represent more than one chunk type, so long as the chunks do not overlap. As we saw earlier, chunk structures can also be represented using trees. These have the benefit that each chunk is a constituent that can be manipulated directly.

An example is shown in 2. As usual, this requires a suitably annotated corpus. We begin by looking at the mechanics of converting IOB format into an NLTK tree, then at how this is done on a larger scale using a chunked corpus. We will see how to score the accuracy of a chunker relative to a corpus, then look at some more data-driven ways to search for NP chunks.

Our focus throughout will be on expanding the coverage of a chunker. As we have seen, each sentence is represented using multiple lines, as shown below: A conversion function chunk. Moreover, it permits us to choose any subset of the three chunk types to use, here just for NP chunks: We can access the data using nltk.

Here is an example that reads the th sentence of the "train" portion of the corpus: As you can see, the CoNLL corpus contains three chunk types: NP chunks, which we have already seen; VP chunks such as has already delivered; and PP chunks such as because of.

We start off by establishing a baseline for the trivial chunk parser cp that creates no chunks: However, since our tagger did not find any chunks, its precision, recall, and f-measure are all zero.

Now let's try a naive regular expression chunker that looks for tags beginning with letters that are characteristic of noun phrase tags e. However, we can improve on it by adopting a more data-driven approach, where we use the training corpus to find the chunk tag I, O, or B that is most likely for each part-of-speech tag.

In other words, we can build a chunker using a unigram tagger 4. But rather than trying to determine the correct part-of-speech tag for each word, we are trying to determine the correct chunk tag, given each word's part-of-speech tag.

Most of the code in this class is simply used to convert back and forth between the chunk tree representation used by NLTK's ChunkParserI interface, and the IOB representation used by the embedded tagger.

The class defines two methods: Noun Phrase Chunking with a Unigram Tagger The constructor expects a list of training sentences, which will be in the form of chunk trees. It first converts training data to a form that is suitable for training the tagger, using tree2conlltags to map each chunk tree to a list of word,tag,chunk triples.

It then uses that converted training data to train a unigram tagger, and stores it in self. The parse method takes a tagged sentence as its input, and begins by extracting the part-of-speech tags from that sentence.2 Samuel "And there happened to be there a man of Belial, whose name [was] Sheba, the son of Bichri, a Benjamite: and he blew a trumpet, and said, We have no part in David, neither have we inheritance in the son of Jesse: every man to his tents, O Israel.".
