Subpackages¶

Submodules¶

alex.applications.PublicTransportInfoCS.autopath module¶

self cloning, automatic path configuration

copy this into any subdirectory of pypy from which scripts need to be run, typically all of the test subdirs. The idea is that any such script simply issues

import autopath

and this will make sure that the parent directory containing “pypy” is in sys.path.

If you modify the master “autopath.py” version (in pypy/tool/autopath.py) you can directly run it which will copy itself on all autopath.py files it finds under the pypy root directory.

This module always provides these attributes:

pypydir pypy root directory path this_dir directory where this autopath.py resides

class alex.applications.PublicTransportInfoCS.hdc_slu.DAIBuilder(utterance, abutterance_lenghts=None)[source]¶

Bases: object

Builds DialogueActItems with proper alignment to corresponding utterance words. When words are successfully matched using DAIBuilder, their indices in the utterance are added to alignment set of the DAI as a side-effect.

all_words_in(words)[source]¶

any_phrase_in(phrases, sub_utt=None)[source]¶

any_word_in(words)[source]¶

build(act_type=None, slot=None, value=None)[source]¶: Produce DialogueActItem based on arguments and alignment from this DAIBuilder state.

clear()[source]¶

ending_phrases_in(phrases)[source]¶

Returns True if the utterance ends with one of the phrases

Parameters:	phrases – a list of phrases to search for
Return type:	bool

first_phrase_span(phrases, sub_utt=None)[source]¶

Returns the span (start, end+1) of the first phrase from the given list that is found in the utterance. Returns (-1, -1) if no phrase is found.

Parameters:	phrases – a list of phrases to be tried (in the given order)
Return type:	tuple

phrase_in(phrase, sub_utt=None)[source]¶

phrase_pos(words, sub_utt=None)[source]¶

Returns the position of the given phrase in the given utterance, or -1 if not found.

Return type:	int

class alex.applications.PublicTransportInfoCS.hdc_slu.PTICSHDCSLU(preprocessing, cfg)[source]¶

Bases: alex.components.slu.base.SLUInterface

abstract_utterance(utterance)[source]¶

Return a list of possible abstractions of the utterance.

Parameters:	utterance – an Utterance instance
Returns:	a list of abstracted utterance, form, value, category label tuples

handle_false_abstractions(abutterance)[source]¶

Revert false positive alarms of abstraction

Parameters:	abutterance – the abstracted utterance
Returns:	the abstracted utterance without false positive abstractions

parse_1_best(obs, verbose=False, *args, **kwargs)[source]¶

Parse an utterance into a dialogue act.

:rtype DialogueActConfusionNetwork

parse_ampm(abutterance, cn)[source]¶

Detects the ampm in the input abstract utterance.

Parameters:	abutterance – the input abstract utterance. cn – The output dialogue act item confusion network.

parse_city(abutterance, cn)[source]¶

Detects stops in the input abstract utterance.

Parameters:	abutterance – the input abstract utterance. cn – The output dialogue act item confusion network.

parse_date_rel(abutterance, cn)[source]¶

Detects the relative date in the input abstract utterance.

Parameters:	abutterance – the input abstract utterance. cn – The output dialogue act item confusion network.

parse_meta(utterance, abutt_lenghts, cn)[source]¶

Detects all dialogue acts which do not generalise its slot values using CLDB.

NOTE: Use DAIBuilder (‘dai’ variable) to match words and build DialogueActItem,: so that the DAI is aligned to corresponding words. If matched words are not supposed to be aligned, use PTICSHDCSLU matching method instead. Make sure to list negative conditions first, so the following positive conditions are not added to alignment, when they shouldn’t. E.g.: (not any_phrase_in(u, [‘dobrý den’, ‘dobrý večer’]) and dai.any_word_in(“dobrý”))

Parameters:	utterance – the input utterance cn – The output dialogue act item confusion network.
