Hi Experts,

I'm now checking my assignments and I would like to ask your opinion on it.

Thank you.

(a) Describe the nature of the ambiguities present in Spell Checking. Recognition) and illustrate with an example. [3 points]

1. semantic ambiguity: words that sound the same but have different meanings and spellings, can pose a challenge for spell checkers. These words can result in incorrect suggestions or missed errors by the spell checking algorithm, as it may mistake a correctly spelled word for an error. An example of this can be seen in the sentence, "I went to their house to see if they were here." In this sentence, the word "their" is used correctly, however, a spell checker may mistake it for the homophone "there" and flag it as an error, due to its inability to distinguish between the two words based on their sound alone.

2. phonological ambiguity: It happens when two words sound the same, but have different meanings. This can make it hard for spell checkers to know which word is the right one. Examples of this are: "hear" and "here", and "knows" and "nose". Phonological ambiguity can also happen when there is more than one way to break up the sound of a word. For example: "John's feat" and "John's feet". In simpler terms, phonological ambiguity means that words that sound the same but have different meanings can cause problems for spell-checking tools.

3. nonstandard spelling: Spell checkers may not be able to detect errors that are contextually correct, such as the use of informal language, regional or dialectal variations, or made-up words. For example, the sentence "I luv u" may not be flagged as an error by a spell checker, even though it uses informal or nonstandard spelling.

4. dependency on dictionaries: Spell checkers rely on dictionaries to identify correct spellings. If the spell checker is trained on a limited or outdated dictionary, it may not be able to recognize new or commonly used words.
