Logical Hebrew ?? +# +# Both "ISO" charsets use a completely identical set of code points, whereas +# "windows-1255" and "x-mac-hebrew" are two different proper supersets of +# these code points. windows-1255 defines additional characters in the range +# 0x80-0x9F as some misc punctuation marks as well as some Hebrew-specific +# diacritics and additional 'Yiddish' ligature letters in the range 0xc0-0xd6. +# x-mac-hebrew defines similar additional code points but with a different +# mapping. +# +# As far as an average Hebrew text with no diacritics is concerned, all four +# charsets are identical with respect to code points. Meaning that for the +# main Hebrew alphabet, all four map the same values to all 27 Hebrew letters +# (including final letters). +# +# The dominant difference between these charsets is their directionality. +# "Visual" directionality means that the text is ordered as if the renderer is +# not aware of a BIDI rendering algorithm. The renderer sees the text and +# draws it from left to right. The text itself when ordered naturally is read +# backwards. A buffer of Visual Hebrew generally looks like so: +# "[last word of first line spelled backwards] [whole line ordered backwards +# and spelled backwards] [first word of first line spelled backwards] +# [end of line] [last word of second line] ... etc' " +# adding punctuation marks, numbers and English text to visual text is +# naturally also "visual" and from left to right. +# +# "Logical" directionality means the text is ordered "naturally" according to +# the order it is read. It is the responsibility of the renderer to display +# the text from right to left. A BIDI algorithm is used to place general +# punctuation marks, numbers and English text in the text. +# +# Texts in x-mac-hebrew are almost impossible to find on the Internet. From +# what little evidence I could find, it seems that its general directionality +# is Logical. +# +# To sum up all of the above, the Hebrew probing mechanism knows about two +# charsets: +# Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are +# backwards while line order is natural. For charset recognition purposes +# the line order is unimportant (In fact, for this implementation, even +# word order is unimportant). +# Logical Hebrew - "windows-1255" - normal, naturally ordered text. +# +# "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be +# specifically identified. +# "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew +# that contain special punctuation marks or diacritics is displayed with +# some unconverted characters showing as question marks. This problem might +# be corrected using another model prober for x-mac-hebrew. Due to the fact +# that x-mac-hebrew texts are so rare, writing another model prober isn't +# worth the effort and performance hit. +# +#### The Prober #### +# +# The prober is divided between two SBCharSetProbers and a HebrewProber, +# all of which are managed, created, fed data, inquired and deleted by the +# SBCSGroupProber. The two SBCharSetProbers identify that the text is in +# fact some kind of Hebrew, Logical or Visual. The final decision about which +# one is it is made by the HebrewProber by combining final-letter scores +# with the scores of the two SBCharSetProbers to produce a final answer. +# +# The SBCSGroupProber is responsible for stripping the original text of HTML +# tags, English characters, numbers, low-ASCII punctuation characters, spaces +# and new lines. It reduces any sequence of such characters to a single space. +# The buffer fed to each prober in the SBCS group prober is pure text in +# high-ASCII. +# The two SBCharSetProbers (model probers) share the same language model: +# Win1255Model. +# The first SBCharSetProber uses the model normally as any other +# SBCharSetProber does, to recognize windows-1255, upon which this model was +# built. The second SBCharSetProber is told to make the pair-of-letter +# lookup in the language model backwards. This in practice exactly simulates +# a visual Hebrew model using the windows-1255 logical Hebrew model. +# +# The HebrewProber is not using any language model. All it does is look for +# final-letter evidence suggesting the text is either logical Hebrew or visual +# Hebrew. Disjointed from the model probers, the results of the HebrewProber +# alone are meaningless. HebrewProber always returns 0.00 as confidence +# since it never identifies a charset by itself. Instead, the pointer to the +# HebrewProber is passed to the model probers as a helper "Name Prober". +# When the Group prober receives a positive identification from any prober, +# it asks for the name of the charset identified. If the prober queried is a +# Hebrew model prober, the model prober forwards the call to the +# HebrewProber to make the final decision. In the HebrewProber, the +# decision is made according to the final-letters scores maintained and Both +# model probers scores. The answer is returned in the form of the name of the +# charset identified, either "windows-1255" or "ISO-8859-8". + +# windows-1255 / ISO-8859-8 code points of interest +FINAL_KAF = '\xea' +NORMAL_KAF = '\xeb' +FINAL_MEM = '\xed' +NORMAL_MEM = '\xee' +FINAL_NUN = '\xef' +NORMAL_NUN = '\xf0' +FINAL_PE = '\xf3' +NORMAL_PE = '\xf4' +FINAL_TSADI = '\xf5' +NORMAL_TSADI = '\xf6' + +# Minimum Visual vs Logical final letter score difference. +# If the difference is below this, don't rely solely on the final letter score distance. +MIN_FINAL_CHAR_DISTANCE = 5 + +# Minimum Visual vs Logical model score difference. +# If the difference is below this, don't rely at all on the model score distance. +MIN_MODEL_DISTANCE = 0.01 + +VISUAL_HEBREW_NAME = "ISO-8859-8" +LOGICAL_HEBREW_NAME = "windows-1255" + +class HebrewProber(CharSetProber): + def __init__(self): + CharSetProber.__init__(self) + self._mLogicalProber = None + self._mVisualProber = None + self.reset() + + def reset(self): + self._mFinalCharLogicalScore = 0 + self._mFinalCharVisualScore = 0 + # The two last characters seen in the previous buffer, + # mPrev and mBeforePrev are initialized to space in order to simulate a word + # delimiter at the beginning of the data + self._mPrev = ' ' + self._mBeforePrev = ' ' + # These probers are owned by the group prober. + + def set_model_probers(self, logicalProber, visualProber): + self._mLogicalProber = logicalProber + self._mVisualProber = visualProber + + def is_final(self, c): + return c in [FINAL_KAF, FINAL_MEM, FINAL_NUN, FINAL_PE, FINAL_TSADI] + + def is_non_final(self, c): + # The normal Tsadi is not a good Non-Final letter due to words like + # 'lechotet' (to chat) containing an apostrophe after the tsadi.
