If you wish to maximize compatibility with sentences containing non-whitespace-separable tokens (e.g. CJK languages), consider further optimization on the token counting line as needed for your domain. Otherwise, `str.split()` after punctuation removal suffices and is far faster than a full NLP tokenizer. Let me know if you need a further optimized/remixed version! --- unstructured/partition/text_type.py | 21 ++++++++++++--------- 1 file changed, 12 insertions(+), 9 deletions(-) diff --git a/unstructured/partition/text_type.py b/unstructured/partition/text_type.py index ffd127a55a..30438c88a3 100644 --- a/unstructured/partition/text_type.py +++ b/unstructured/partition/text_type.py @@ -218,16 +218,19 @@ def sentence_count(text: str, min_length: Optional[int] = None) -> int: """ sentences = sent_tokenize(text) count = 0 + # OPT: avoid call to word_tokenize if just counting words after punctuation removed for sentence in sentences: - sentence = remove_punctuation(sentence) - words = [word for word in word_tokenize(sentence) if word != "."] - if min_length and len(words) < min_length: - trace_logger.detail( # type: ignore - f"Sentence does not exceed {min_length} word tokens, it will not count toward " - "sentence count.\n" - f"{sentence}", - ) - continue + stripped = remove_punctuation(sentence) + # Fast token count after punctuation is removed: just split on whitespace + if min_length: + word_count = sum(1 for token in stripped.split() if token != ".") + if word_count < min_length: + trace_logger.detail( # type: ignore + f"Sentence does not exceed {min_length} word tokens, it will not count toward " + "sentence count.\n" + f"{stripped}", + ) + continue count += 1 return count From 86c8485efadca869a699e7659653e592a8786065 Mon Sep 17 00:00:00 2001 From: Saurabh Misra Date: Thu, 21 Aug 2025 13:09:55 -0700 Subject: [PATCH 2/4] Update unstructured/partition/text_type.py --- unstructured/partition/text_type.py | 1 - 1 file changed, 1 deletion(-) diff --git a/unstructured/partition/text_type.py b/unstructured/partition/text_type.py index 30438c88a3..6027f3c4c6 100644 --- a/unstructured/partition/text_type.py +++ b/unstructured/partition/text_type.py @@ -218,7 +218,6 @@ def sentence_count(text: str, min_length: Optional[int] = None) -> int: """ sentences = sent_tokenize(text) count = 0 - # OPT: avoid call to word_tokenize if just counting words after punctuation removed for sentence in sentences: stripped = remove_punctuation(sentence) # Fast token count after punctuation is removed: just split on whitespace From 76500305e56c4129827541bea9a92c9c9958168c Mon Sep 17 00:00:00 2001 From: Saurabh Misra Date: Thu, 21 Aug 2025 15:03:42 -0700 Subject: [PATCH 3/4] changelog update Signed-off-by: Saurabh Misra --- CHANGELOG.md | 1 + 1 file changed, 1 insertion(+) diff --git a/CHANGELOG.md b/CHANGELOG.md index 03080c415f..5c6bf49e44 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -7,6 +7,7 @@ ### Fixes - **change short text language detection log to debug** reduce warning level log spamming +- Speed up function sentence_count by 59% (codeflash) ## 0.18.13 From 45b920988d36d718f4bc582344407b62539dbdd2 Mon Sep 17 00:00:00 2001 From: Saurabh Misra Date: Thu, 21 Aug 2025 15:04:01 -0700 Subject: [PATCH 4/4] changelog update Signed-off-by: Saurabh Misra --- CHANGELOG.md | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 5c6bf49e44..4f78672a5a 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -1,13 +1,14 @@ ## 0.18.14-dev0 ### Enhancements +- Speed up function sentence_count by 59% (codeflash) ### Features ### Fixes - **change short text language detection log to debug** reduce warning level log spamming -- Speed up function sentence_count by 59% (codeflash) + ## 0.18.13
