问题 How can I obtain all the chunk from a sentence given a pattern. Exemple NP:{<NN><NN>} Sentence tagged: [("money", "NN"), ("market", "NN") ("fund", "NN")] If I parse I obtain (S (NP money/NN market/NN) fund/NN) I would like to have also the other alternative that is (S money/NN (NP market/NN fund/NN)) 回答1: I think your question is about getting the n most likely parses of a sentence. Am I right? If yes, see the nbest_parse(sent, n=None) function in the 2.0 documentation. 回答2: @mbatchkarov is

File slicing in JavaScript results in empty blob

问题 I am implementing a browser-based chunked file uploader. To open the file I am using <input type="file" id="fileSelector" /> and this piece of code (simplified): $('#fileSelector').on('change', function () { _file = evt.target.files[0]; }); I am slicing the file into chunks, but not reading the chunk into memory (not explicitly). Problem : occasionally (for less than 0.1% of uploaded files) the chunk sliced from the underlying file is empty. E.g. during uploading a large file things go well,

download file client-side chunk by chunk

问题 I'm using WebRTC to send a file to a connected peer, and I'm sending the file in chunks. However, I'm having trouble figuring out how to get the peer to save/download the file as it is streaming in, chunk by chunk. All the examples I've found online recommend doing something like this: // sender dataConnection.send({ 'file': file }); // receiver dataConnection.on('data', function(fileData) { var dataView = new Uint8Array(fileData); var dataBlob = new Blob([dataView]); var url = window.URL

Rechunk a conduit into larger chunks using combinators

由 夙愿已清 提交于 2019-12-04 02:52:01
I am trying to construct a Conduit that receives as input ByteString s (of around 1kb per chunk in size) and produces as output concatenated ByteString s of 512kb chunks. This seems like it should be simple to do, but I'm having a lot of trouble, most of the strategies I've tried using have only succeeded in dividing the chunks into smaller chunks, I haven't succeeded in concatenating larger chunks. I started out trying isolate , then takeExactlyE and eventually conduitVector , but to no avail. Eventually I settled on this: import qualified Data.Conduit as C import qualified Data.Conduit

Decoding chunked HTTP with Actionscript

由 那年仲夏 提交于 2019-12-03 23:05:30
问题 I have successfully connected to an HTTP server with ActionScript 3 over sockets. The only problem is, the server is sending chunked HTTP. Is there a generic function in any other language I can look at that clearly shows how to decode the chunking? I'm pretty sure there are no ActionScript libraries around for this. 回答1: The HTTP 1.1 specification (or from W3C) provides a pseudocode example of how to decode chunked transfer-coding: length := 0 read chunk-size, chunk-extension (if any) and
