For the second version of our shared task, we propose two sub-tasks; Task A is a Qur'anic passage retrieval (PR) task, while Task B is a machine reading comprehension (RC) task. We describe and formally define Task A below.
Task Definition
Task Definition
The task is defined as follows: Given a free-text question posed in MSA and a collection of Qur'anic passages that cover the Holy Qur'an, a system is required to return a ranked list of answer-bearing passages (i.e., passages that potentially enclose the answer(s) to the given question) from this collection. The question can be a factoid or non-factoid question. An example question is shown below.
To make the task more realistic (thus challenging), some questions may not have an answer in the Holy Qur'an. In such cases, the ideal system should return no answers; otherwise, it returns a ranked list of up to 10 answer-bearing Qur'anic passages.

(2:87-88) وَلَقَدْ ءَاتَيْنَا مُوسَى ٱلْكِتَٰبَ وَقَفَّيْنَا مِنۢ بَعْدِهِۦ بِٱلرُّسُلِ وَءَاتَيْنَا عِيسَى ٱبْنَ مَرْيَمَ ٱلْبَيِّنَٰتِ وَأَيَّدْنَٰهُ بِرُوحِ ٱلْقُدُسِ أَفَكُلَّمَا جَآءَكُمْ رَسُولٌۢ بِمَا لَا تَهْوَىٰٓ أَنفُسُكُمُ ٱسْتَكْبَرْتُمْ فَفَرِيقًا كَذَّبْتُمْ وَفَرِيقًا تَقْتُلُونَ. وَقَالُوا۟ قُلُوبُنَا غُلْفٌۢ بَل لَّعَنَهُمُ ٱللَّهُ بِكُفْرِهِمْ فَقَلِيلًا مَّا يُؤْمِنُونَ.
(2:97-101) قُلْ مَن كَانَ عَدُوًّا لِّجِبْرِيلَ فَإِنَّهُۥ نَزَّلَهُۥ عَلَىٰ قَلْبِكَ بِإِذْنِ ٱللَّهِ مُصَدِّقًا لِّمَا بَيْنَ يَدَيْهِ وَهُدًى وَبُشْرَىٰ لِلْمُؤْمِنِينَ. مَن كَانَ عَدُوًّا لِّلَّهِ وَمَلَٰٓئِكَتِهِۦ وَرُسُلِهِۦ وَجِبْرِيلَ وَمِيكَىٰلَ فَإِنَّ ٱللَّهَ عَدُوٌّ لِّلْكَٰفِرِينَ. وَلَقَدْ أَنزَلْنَآ إِلَيْكَ ءَايَٰتٍۭ بَيِّنَٰتٍ وَمَا يَكْفُرُ بِهَآ إِلَّا ٱلْفَٰسِقُونَ. أَوَكُلَّمَا عَٰهَدُوا۟ عَهْدًا نَّبَذَهُۥ فَرِيقٌ مِّنْهُم بَلْ أَكْثَرُهُمْ لَا يُؤْمِنُونَ. وَلَمَّا جَآءَهُمْ رَسُولٌ مِّنْ عِندِ ٱللَّهِ مُصَدِّقٌ لِّمَا مَعَهُمْ نَبَذَ فَرِيقٌ مِّنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ كِتَٰبَ ٱللَّهِ وَرَآءَ ظُهُورِهِمْ كَأَنَّهُمْ لَا يَعْلَمُونَ.
(2:102-103) وَٱتَّبَعُوا۟ مَا تَتْلُوا۟ ٱلشَّيَٰطِينُ عَلَىٰ مُلْكِ سُلَيْمَٰنَ وَمَا كَفَرَ سُلَيْمَٰنُ وَلَٰكِنَّ ٱلشَّيَٰطِينَ كَفَرُوا۟ يُعَلِّمُونَ ٱلنَّاسَ ٱلسِّحْرَ وَمَآ أُنزِلَ عَلَى ٱلْمَلَكَيْنِ بِبَابِلَ هَٰرُوتَ وَمَٰرُوتَ وَمَا يُعَلِّمَانِ مِنْ أَحَدٍ حَتَّىٰ يَقُولَآ إِنَّمَا نَحْنُ فِتْنَةٌ فَلَا تَكْفُرْ فَيَتَعَلَّمُونَ مِنْهُمَا مَا يُفَرِّقُونَ بِهِۦ بَيْنَ ٱلْمَرْءِ وَزَوْجِهِۦ وَمَا هُم بِضَآرِّينَ بِهِۦ مِنْ أَحَدٍ إِلَّا بِإِذْنِ ٱللَّهِ وَيَتَعَلَّمُونَ مَا يَضُرُّهُمْ وَلَا يَنفَعُهُمْ وَلَقَدْ عَلِمُوا۟ لَمَنِ ٱشْتَرَىٰهُ مَا لَهُۥ فِى ٱلْءَاخِرَةِ مِنْ خَلَٰقٍ وَلَبِئْسَ مَا شَرَوْا۟ بِهِۦٓ أَنفُسَهُمْ لَوْ كَانُوا۟ يَعْلَمُونَ. وَلَوْ أَنَّهُمْ ءَامَنُوا۟ وَٱتَّقَوْا۟ لَمَثُوبَةٌ مِّنْ عِندِ ٱللَّهِ خَيْرٌ لَّوْ كَانُوا۟ يَعْلَمُونَ.

Evaluation Measures
Evaluation Measures
As the PR task is a classical ranked retrieval task, Mean Average Precision (MAP) will be used as the main official measure for evaluation. The no answer cases will be handled simply by giving full credit to ``no answers'' system output and zero otherwise.
The Mean Reciprocal Rank (MRR) will also be reported.
