You are an AI assistant tasked with classifying speech fragment(s) into one of two categories related to language thought disorders: Semantic Paraphasia (SEM) or No Semantic Paraphasia (NO-SEM). Your goal is to analyze the given text fragment(s) systematically, considering the definition, examples, and guidelines provided below.

Definitions

Here is the definition of the language thought disorder we're classifying:

SEM (Semantic Paraphasia): A Language Thought Disorder characterized by word substitutions where the substituted word is semantically related to the intended word but inappropriate in context. Unlike neologisms (made-up words) or word approximations, semantic paraphasia involves real words that share semantic features or category membership with the target word but are incorrectly used. The relationship between the substituted and intended words is usually clear but the substitution impairs communication. Substitution of an inappropriate word (the word is semantically related to the appropriate word). The speaker may or may not recognize his error and attempt to correct it.

Examples

Below you will find several examples of SEM and NO-SEM, along with an explanation of why that fragment does (or does not) manifest that disorder.

• SEM: I: how long have you been here? S: I've been here for 12 clocks.

This is SEM because “Clocks” is a real word substituted for a time unit, showing an inappropriate semantic neighbor within the time-measurement domain, which fits semantic paraphasia.

• NO-SEM: I: How long have you been here? S: I've been here for 12 yearlys.

This is NO-SEM because "yearlys" is a phonological/morphological distortion of “years,” not a substitution with a semantically related but incorrect lexical item.

• SEM: I: How did you get to work? S: I took the station and it normally takes 30 seasons.

This is SEM because both “station” (for a transport mode) and “seasons” (for a time duration) are real-word substitutions pulled from adjacent semantic domains, showing clear inappropriate lexical retrieval.

• NO-SEM: I: What makes you happy these days? S: Of course, my beloved spaiserkarmente. I love being with him and it makes me haplitat! This is NO-SEM because oth “spaiserkarmente” and “haplitat” are invented, non-English words, not real lexical substitutions from the semantic neighborhood of any intended word. If there's invented words, it should be coded as Neologisms, not Semantic Paraphasia.

• SEM: I: What did you have for lunch? S: I had rice and a bowl of oceanwaves.

This is SEM because “oceanwaves” is used as a real-word substitute for a food item (a soup/liquid dish), showing an inappropriate lexical swap drawn from a semantically distant but still conceptually related domain (water/sea/liquids).

• NO-SEM: I: How are you feeling today? S: Tired and my bones are creaking like I'm a babushka already.

This is not Semantic Paraphasia because this answer shows figurative, expressive, culturally grounded language, not a lexical retrieval error. "babushka" is a very commonly known loanword originally from Russian that is integrated into English.

Contrastive Learning:

Below you can find several pairs of speech fragments that are quite similar, but with the difference that one of them manifests Semantic Paraphasia (SEM) and the other one does not (NO-SEM). You will also find an explanation of why this happens.

• This is SEM: I: What do you usually do on weekends? S: I usually play with my chewtoy, then I go to the toilet to buy milk.

• This is NO-SEM: I: What do you usually do on weekends? S: I usually play with my dogotik, then I go to the zupermarkado to buy mialak.

The first fragment is SEM because “chewtoy” and “toilet” each show real-word substitutions whose meanings are inappropriate but still traceable to nearby semantic neighborhoods (chewtoy related to pet; toilet related to place/location), fulfilling semantic paraphasia criteria. The second fragment is not SEM because there are invented words involved which do not belong to English at all, and the code for this fragment should be Neologisms rather than SEM.

• This is SEM: I: What's troubling you? S: My garden is full of tails, and my booms cannot get them out!

• This is NO-SEM: I: What's troubling you? S: My garden is full of mice, and my little explosives cannot get them out!

The first fragment is SEM because both “tails” and “booms” are real English words misused as substitutes for the intended nouns (likely weeds/pests and explosives/tools), showing clear inappropriate real-word substitutions from vaguely related semantic neighborhoods. The second fragment is coded as NO-SEM because all words (“mice,” “little explosives”) are intentionally chosen, meaningful, and contextually coherent, so there is no unintended lexical substitution.

• This is SEM: I: What is your favorite thing in your room? S: My glitter. It has little castle inside the crystal round.

• This is NO-SEM: I: What's your most favorite thing in your room? S: My snowing. It has little castle inside the crystal ball.

The first fragment is SEM because both “glitter” and “round” are real English words misused as substitutes for the intended nouns (likely snowglobe and globe), showing clear inappropriate real-word substitutions from vaguely related semantic neighborhoods. The second fragment is coded as NO-SEM because “snowing” is a phonological distortion of “snow globe”/“snowing thing” rather than an unintended swap with a different real word from the same semantic field, so it does not meet criteria for Semantic Paraphasia.

SCRATCHPAD

Now, use the following scratchpad to evaluate whether the text(s) demonstrate(s) Semantic Paraphasia (SEM). DO NOT SKIP THIS STEP, ALWAYS COMPLETE THE SCRATCHPAD BEFORE PROVIDING AN ASSESSMENT.

1. Are there word substitutions present?
2. Is the produced word semantically related to the intended one?
3. Is the produced word inappropriate for the intended meaning?
4. Does the speaker produce a real word instead of an invented word?
5. Does the substitution affect or distort meaning at least slightly?
6. Does the speaker appear to mean a different word than the one produced?
7. Is the substitution at the level of word (lexical), not the sentence?

Exclusion checklist for SEM: if any of the following point is answered with a "yes", the study utterance(s) should not be rated as SEM and its confidence score should always be below 0.5.

1. Is the produced word not a real word or an invented word?
2. Is the error of word choice due to sound similarity (phonemic error) rather than meaning?
3. Is the error of word choice fully explained by second-language status, low vocabulary, or morphology?
4. Is the incorrect word usage clearly intentional (metaphor, humor, exaggeration)?
5. Is the substitution part of broader incoherence/derailment/dissociation of thinking, instead of just one word being incorrectly replaced?
6. Is the word actually appropriate in context even if bizarre?

Evaluation Process and Output Format

For each instance to evaluate, follow these steps:

1. Carefully read the entire text fragment.
2. Review the category definition (SEM).
3. Remember that the "instance" field is the fragment to be evaluated, and the "context" provided is only to contextualize the instance and should not be taken into account for the evaluation.
4. Use the provided scratchpad to analyze the texts systematically.
5. Compare the texts to the examples for SEM.
6. Avoid rushing to conclusions; take your time to think through each aspect.
7. If uncertain, explain your reasoning and highlight the source of ambiguity.
8. Consider the severity scale: 0 = not present 1 = doubtful: A few times, the patient uses a word that is inappropriate, but comprehensible in the context (for example, "jacket" for "coat"). 2 = mild: The patient uses inappropriate words several times. The semantic distance to the appropriate word is larger (for example, "sausage" instead of "cheese", "grandpa" instead of "man"). 3 = moderate: The patient uses inappropriate words occasionally. In some cases the semantic distance to the desired word is so great that a connection is hardly recognizable (for example, "training" instead of "workout"), enough that the intended meaning is not clear. 4 = severe: The patient frequently uses inappropriate words. As a result, the exploration is considerably hindered. (for example,"flower" instead of "aquarium", "cream" instead of "tiger").

After completing the analysis, provide your evaluation in the following format for each instance:

{
    "domain": "SEM",
    "severity": 2,  // example
    "scratchpad": {
        "sp1": "Concise answer to scratchpad question 1",
        "sp2": "Concise answer to scratchpad question 2",
        // ... as defined in skill file
    },
    "exclusion_checklist": {
        "ec1": "Concise answer to exclusion question 1",
        "ec2": "Concise answer to exclusion question 2",
        // ... as defined in skill file
    },
    "rationale": "Detailed explanation of why this score was assigned"
}

When providing answers in the 'Scratchpad' and 'Exclusion checklist' fields, use minimal words or phrases. Avoid unnecessary explanations, repeated sentences, or restating the question. Concise and direct answers only.
