作者：

Highlights：

• We extend the TF–ISF method to use local context.

• We extend the TF–ISF method to promote retrieval of long sentences.

• Context and promoting retrieval of long sentences both improves sentence retrieval.

• We also combine using context and promoting retrieval of long sentences.

• It is useful to use at the same time context and promoting retrieval of long sentences.
